    “Ink,but doesnt american Abrams have gas turbine as an engine?”

    Indeed it does. But that doesn’t mean it runs on gas. It works exactle like an aircraft jet engine, only it’s purpose is not to produce thrust, it is to produce power, like in an aircraft APU. You suck in air, compress it, burn fuel in oit (That could be gas… possibly!) then expand it though a turbine to power the compressor, then send the air through another power turbine to take as much power from the air as you possibly can… leaving negligible thrust, as you don’t need it to move the tank so thrust is a waste of power for the tanks purpose.

    I wish I could keep up 80MPH on the M1 between Leeds and Loughborough!!!!! There’s way too much traffic!!

    Last time I drove it… I was in the centre lane overtaking… at around 70… undertaking traffic in the outside lane! Bizarre!

    “I was on that flight, cabin crew were excellent, everyone evacuated within 2 minutes “

    Abyssmal performance… the airline deserve to be fined! Everyone should have been off 30 seconds sooner!

    The one problem with a blended wing civil airliner is the emergency exits. Civil aircraft have to be able to get everyone off in 90 seconds using half the exits. So, the position of exits is limited to the leading edge… or the trailing edge (You could put them in the floor… but what happens if the landing gear collapses!).

    Any of those adverts for clearing your debts… one thing they don’t mention is that you have to sign your house over to them and if you can’t pay… goodbye house… whereas if you stick with the credit card…. they can’t chuck you out of your house!

    And also the ads for personal injury claims!

    Yup… Just a mechanic with a screwdriver… which is exactly what would be used in the manufacturing of the aircraft… It’ll be a case of “Yeah, that’s tight… that’ll do… rather than actually measuring the exact torque on the screw.

    Thankyou very much!!

    The engine I’m hoping to do a preliminary design for is supposed to be an advanced trainer/attack fighter (single engine) at Mach 0.75, at sea level. What my lecturers were thinking of when they set this I have no idea… with 1900lb of thrust you can’t exactly carry much!

    “The tail rotor does nothing during autorotation”

    Surely you need it to make sure you can auto-rotate in a straight line??

    “i looked in a twenty year old plane book ive got about future fighters and stuff and it shows the hughes notar in cross section and from the engine there is a shaft to the big fan in the fat tail boom. if the engine stopped, i think this fan would stop?”

    In a gas turbine engine, the parts are allowed to move, very freely. So if the engine did cut out… it would still turn over, and because the helicopter maintains forward speed under auto-rotation, there is still air going through the engine to turn the engine blades. This means that that fan providing power for the NOTAR would still turn.

    Just though of something else actually….. The NOTAR fan could be connected to the main rotor system, so these could power it in an emergency… like auto rotation. Just a thought!

    In later versions of the F-105, was there still a bomb bay? If so… what was the centreline weapons pylon bolted to??

    Here’s a thought… How easy would it be to bring an airliner down by starting a fire? I guess you could get it going in the toilets… and before you talk about smoke detectors… anyone can solve that… it’s called cling film! Should all cigarette lighters and matches be banned from aircraft?

    A few years ago, when RR were testing the RB.211, my dad was doing some electrical work at the RR test facility. That day, RR were testing the RB.211 for different fuels, to see what it could run on… they came up with a few types… but after lunch, there was a huge explosion… the RB.211 didn’t agree with this particular fuel and it blew the whole back wall out of the building!
